Borrowers and lenders list and bid for loans on Prosper, an eBay-like auction site that helps process loans of up to $25,000. Interest rates depend on a person's credit history and other criteria - lenders have access to a borrower's personal story, endorsements from friends and photos.

Prosper has 830,000 members.
